MACHINE FOR APPLYING METALLIC LEAF TO BOOK-COVERS OR THE LIKE.

Patented July 11, 1916.

Application filed April 24, 1913. Serial N0. 763,281.

To all whom it may concern:

lie it known that I, Cnanmis E. SMITH, a citizen of the United States, residing at Oak Lawn. in the county of Providence and State of Rhode Island, have invented a new and useful Machine for Applying Metallic Leaf to liookllovers or the like, of which the following a specification.

My invention relates to an improved m. chino for depositing metallic leaf upon book covers or the like from a package roll, and it consists in the means hereinafter fully described by which the right amount of metallic leaf is drawn from the roll containing it and applied to the book cover or other article.

in the accompanying drawing: Figure 1 represents a front elevation of the machine. Fig. 2 represents a top view of the same. Fig. 3 represents a side view. Figs. 4 and 5 represent detail views of the adjustable means for drawing the paper strip forward to the extent required. Fig. 6 represents an enlarged detail view showing the depositing means in its open position. Fig. 7 represents the same when in its lirst closed position. Fig. 8 represents a section taken in the lino of Fig. (3. Fig. 9 represents the mmewhen in its second closed position. Fig. 10 represents the same when in its third closed position in which the deposited metallic leaf will be, separated from that remaining in the. roll. Fig. ll represents a detail view showing an edge view of the pa kage roll. and a forward end view of the depositing jaw. Fig. 12 represents a section taken in the line l2. 12. of Fig. 10. Fig. 1.3 represents a section taken in the line 13, 13 of Fig. 10. Fig. ll represents the application of suction to the depositing jaw. Fig. 15 represents a detail section taken in the line 1?. 15. of Fig. ll. Fig. 16 represents a plan view of the under side of the depos iting jaw.

In the drawing represents the frame of the machine, 1) the driving shaft upon which is placed the. bevel pin on G, the said shaft 13 being driven from the pulley D on the shaft E by means of a worm and worm gear. The support for the, book cover or other article to which the metallic leaf is to be applied is formed by the reciprocating and rocking jaw F which is joined to a sliding block Gr held for reciprocation between the guide-ways H, H, of the frame the said jaw being operated in its up and down and rocking movement, by means of the crank pin I, attached to the disk I, which is keyed to the end of the shaft 13. The support. for the strip of metallic leaf which is drawn from the roll by mechanism to be described is formed by the depositing jaw J provided with a shank K which is guided in its vertical movement by the guide-ways L, L, and. is forced downwa d by means of the spring M against the stoppin N,'which is inclosed by the slot 0 in the said shank. The shank K of the depos iting jaw J, is held between the said guideways L, L, by means of the latch piece P. which is pivoted at the screw Q, and limited in its pivotal movement by means of the pin R. The package roll of metallic leaf S is held for rotation upon a stud T, attached to the shank K, and is held upon said stud by means of the spring U as shown in Fig. 12.

.n Fig. i), the rocking jaw F and the yielding jaw J, are represented in their highest position with the paper strip and metallic leaf which has been drawn from the package roll S, pressed flatly between them; but the continued movement of the crank pin I will cause the deflection of the rocking jaw F and a slight backward movement at the angular edge V of the depositing jaw, whereby the metallic leaf \V which at this point is under the supporting paper strip X will become crushed or disintegrated and thereby cause the separation of the portion Y when deposited upon a book cover from the portion Z, which remains with the package roll.

In order to prevent the falling of the metallic leaf \V from the supporting paper strip X when the same is held in the position shown in Figs. 6 and 7 I provide the face (I, of the depositing jaw J with openings 1), b, which connect with the vacuum' cham her 0, from which the air is drawn by means of the suction pipe 0, as shown in Figs. 14,

15 and 16.

The book cover is placed upon the jaw F when the same is in the position shown in Fig. 6 and is then carried up to contact with the depositing jaw J to receive the deposit of metallic leaf, as shown in Fig. 7. The construction of the sliding block G to which the rocking jaw F is jointed. is shown in the section Fig. 8.

.ward from the In order to be able to feed the strip of metallic leaf between the jaws F and J and to vary the length of the strip of metallic leaf to be deposited upon the book covers, as desired, I provide a rubber covered feed roll 7, shown in Figs. 2, 3, and 4, which is driven from the shaft B, by means of the bevel pinion C, the bevel gear 9, the oblique shaft 71,, the bevel gear i, and the bevel pinion 7'. Upon the shaft in, which is held in sliding boxes Z, l, so as to be movable toward and from the feed r011 f, is secured the cams m, m, which contact with the end flanges m of the roll f, and which serve to impart an outward movement to the said shaft k against the resilient action of the actuating spring n of the sliding boxes, and upon said shaft 70 is placed the adjustable feeding segments 0, 0, which when brought into contact with the feed roll 7 serve to draw the paper strips and metallic leaf for package rolls, S, S. The said paper X, h, from which the metallic leaf has been deposited are slightly held against the periphery of the feed roll 7, by means of the rollers 72, p, which are secured to the loose shaft 9.

A gear a fast on the roll 7, and driven from the gear 2', engages a gear 6 on the shaft [6. The dimensions of the gears a and b are such that the peripheral speed of the roll f, to which the gear a is attached, is the same as the eripheral speed of the segments 0 attached to the shaft in.

The rollers p,-p, bear very slightly against the paper strip upon the feed roll, and serve merely to keep the strips in place when they are not engaged by the segments 0 and they do not operate to cause the forward movement of the paper strips with the continuously moving periphery of the feed roll,

The cams m, m, slidably contact with the flanges m of the feed roll f, but do not rotate the latter. The segments 0, 0, are made adjustable upon the shaft is, with reference to the position of the cams thereon, and with relation to each other, by means of the clamp (Z', and by means of such adjustment the segments may be caused to engage for a greater or less extent with the feed roll f. During the time that the segments 0, 0, are not in contact with the roll they do not feed the strip, and while the high. portion of the cam m is in contact with the flange m the book support is being lifted up against the strip and the operation of attaching the gold leaf to the book is accomplished; during this time the segments 0, 0,

are not in contact with the roll f. The segment 0 may be so adjusted that a portion of it passes by the roll f during this period, but whatever amount of the segment 0 is, by the presentation of the depressed por- 66 tion of the cam m to the flange m of the roll f, allowed to come in contact with the strip on the roll 2 so much of the segment feeds the paper strip and by adjusting the segment on the shaft Zr: the amount of the segment in contact with the roll f and the consequent feed of the paper strip may be varied. The depositing jaws J, .l, and the accompanying package rolls of metallic leaf S, are adjustahly secured to the slotted projecting bracket 2' by any suitable means.

\Vhen the machine is set in operation the adjustable feeding segments 0, 0, will he carried forward through the action of the springs n of the sliding boxes l, to surface contact with the paper strip upon the feed roll f, and cause a length of the paper strip to be advanced. the length of which advance is determined hy the radial adjustment of the feeding segments on the shaft 11:. This adjustment may be measured by marginal graduations t on the segment faces, and if desired, some fixed member adjacent the segment such as the cross bar a may be employed as the relatively fixed point for such adjustment. The paper stri in its passage over the angular edge V o the de positing jaw, and between the rubber cov ered feed roll f, and the peripheries of the segments 0, develops a degree of frictional electricity which requires removal in order to properly dispose of the said strip, and to this end the paper strip X is passed over a hot metal plate 2:, which may be heated by means of an electric heater to. The driving clutch a is carried into engagement by pressing down upon the pedal, y, and is withdrawn from engagement by the resiliency of the spring 2, and may be automatically disengaged at the completion of its cycle of revolution Supplementary to the main advantages of the machine already disclosed by the description in laying metallic leaf automatically from a single strip, the following advantages will be noted in the use of the machine for applying leaf from a plurality of strips. In manv instances, as in book cover gilding, the gold should be laid in as many transverse parallel lines thereon as there is intended to be lines of gold lettering, and these lines are often and usually of length differing from each other because of the difference in the number of words, ornaments, or letters contained in each particular line.

One advantage of the machine is the capacity to lay a plurality of strips simultaneously as well as automatically Another advantage is to space the gold leaf according to the spacing of the lines on the book. A third a d antage is to start the application of the gold leaf at the several dilferent necessary distances in from the right hand margin of the cover.

necessary different distances in from the left A further advantage is to end the 21)}Jl1tf2llll0ll of the several leaves hand margin of the cover. Another advantage is that 1 am enabled to maintain the several supporting strips in parallelism on the machine and prei'ent their accidental disengagement therefrom.

The first advantage above referred to is attained by laying the book or book cover or article on the support F transversely of the lines of travel of the gold leaf strips; and then having a plurality of supports J, corres onding with the number of lines required by the particular book cover, arranged in series on the bar 1-. In the present case, three supports onl are shown simultaneously controlling -t ree strips X for application to three lines. Therefore, there must be, as shown, three segments 0, to transversely draw forward or feed the three strips.

The second enumerated advantage is attained by making the supports J longitudi nally adjustable to each other on bar 7'. This bar has a longitudinal slot 015' through which loosely pass bolts a whose heads a rest upon washers a on the bar, and whose threaded ends enter threaded cavities 0: (see Fig. 11) in the guides or hangers L. Between the bar and each hanger is a bolster embracing the bar and provided in its lower face with a. seat o for the member L. The bolster is provided centrally with an oblong slot lengthwise of the bolster (not visible in the drawings) through which the bolt (1 passes. By loosening the bolts it will be seen that the three supports may he slid longitudinally oi the bar 1- and be clamped thereon at any distance required to register with any line on the book cover. This adjustment is facilitated by the scale a on the bar 7'.

The third enumerated advantage is attained by the transversely adjustable character oi the supports .l relatively to nch other in the line of travel of the strips X, whereby the Vshaped ends of the supports, which cooperate with the jaw F to cut and initiate the application of the severed gold leaf. extend to the right different distances. To effect the transverse movement of the members L it will be observed that the slot (1. is much liiroader than the bolt (L3, and the central oblong slot in the bolster is provided. For the purpose of simultaneously adjusting all of the supports J relatively to the right hand margin of the book cover or article. the end oi the bar 7" is provided with transverse slots (1. to accommodate adj usting screws (1. engaging in threaded holes a." in the machine frame.

In attaining the fourth advantage the following elements enter, namely, the lcngi l1 oi the section of severed gold leaf and the distance that its supporting strip had pre viously been advanced by the bolt of its particular cam. The length of each poll is equal to the length of the particular i' on the book to he roicrcd by th ni. r leaf, which. alrcri when does not corrcsponrl Willi the lcn u'tl; oi' the remaining lines. To initially (.lttlQi'illllit. the length of pull, the line on the book is lirst measured and that measurement in inches determines the degree in inches oi' the radial adjustment of the particular feeding segment 0. It is adyantageous but not essential to employ supports J liming the exact lengths oi the several cut lent lengths. A supply of shoes or supports J of dili'er ent lengths, and the readily adjustable character of the members L, K, makes substitution easy.

The fil'th advantage above enumeratedis attained by the scale I," on the cross-bar a, used in conjunction with the scale a on the arm 1". That is, the relative locations of the supports J are determined on the latter scale, and the several segments 0 and rolls ,0 a re then located at corresponding distances on the scale Z1 It is important that the segments and supports be arranged in alinement because should they be by accident arranged substantially otherwise the strips X would assume diagonally disposed positions across the machine, and would be accidentally released from the segments when the elevations of the cams on were in contact with the flanges m.
